摘要：

In the best light: Plasmonic gold substrates were used to image cells by near-infrared fluorescence microscopy. Two fluorophores (single-walled carbon nanotubes (SWNTs) functionalized by the RGD sequence as well as the organic fluorophore IR800) tag cells in two different spectral regions. The fluorescence of SWNTs sandwiched between a cell membrane and a gold film was enhanced relative to the fluorescence observed on a quartz substrate (see picture). © 2011 WILEY-VCH Verlag GmbH & Co.
